Basic parts of the filter press:

The frame forms the supporting structure of the whole unit. The filtration plates are suspended on it making the filter press rigid to withstand strong force loading during the working cycle. The filtration plates form the working room of the filter press – a system of closed filtration chambers. The side of the plate is thicker than the internal recessed part and thus it creates contact surfaces with the adjacent plate. The filtration chamber is always made up of two adjacent plates, the thickness of the chamber is determined by a sum of their recessions. The filtration plates are covered with filtration clothes. The dewatered suspension is conveyed through the inlet opening passing through the whole set of plates and clothes. The liquid is distributed evenly by pressure to all chambers, the filtrate passes through the clothes and is drained via channels drilled in the plates. During the filtration, the set of plates is firmly clamped using ahydraulic unit. This secures that suspension cannot leak out of the filtration chambers even at high filtration pressure.

At the customer's request, or if required so from the technological point of view, the filter presses may be equipped with a number of accessories and equipment. 

Along with the delivery of our equipment we guarantee delivery of operating documentation, training of personnel and service staff , guarantee and post-guarantee services , and technical assistance.

Division of filter presses based on the type of filtration plates

Filter press with plates and frames (frames and plates separately)

Chamber

Membrane (chamber-membrane)

As a standard, the filtration plates are manufactured from PP, other materials may be used based on the process.

Method of filtrate draining

Open

Close

400 x 400 mm - 2000 x 2000 mm

Volume of the filter press chambers

Usually in a range of 20 dm3 - 9000 dm3

Filtration surface

Usually in a range of 1,8 m2 - 650 m2

Thickness of the filtration chamber

Usually 10 – 50 mm

Filtration pressure

the standard pressure is 16 bar, we also produce filter presses for filtration pressures up to a maximum of 30 bar

Achieved dry solids content in the filtration cake

Usually 20 – 50%, with some suspensions as much as 80 - 90%

Filtration clothes

Monofilament

Multifilament

Mono-multifilament

The clothes are available in several alternatives of materials

Hydraulic system

with a single acting or double acting hydraulic cylinder

closing by a manual hydraulic pump or an electro hydraulic unit

Plates shifting

Manual

Automatic (individually plate by plate, several plates together, all plates by one stroke of the hydraulic cylinder)

Other optional equipment and accessories for the filter press

Filter press models

The table below shows only indicative information for the filtration chamber thickness of 25 mm. As regards the membrane design, the volume stated is the volume before squeezing the membranes. A

Precise dimensions of the filter press and further information (e.g. performance parameters, description of the equipment) will be specified in the offer based on your specific instructions. The filter presses are always designed with respect to the quantity, origin, composition and characteristics of dewatered suspension.
